Question

Two identical heaters 240 V – 1000 W are connected in series across a supply of 240 V line, then the combined power is. (a) 2000 W (b) 1000 W (c) 500 W (d) 4000 W i want only right answer then i mark you brainliest no wrong answers i can report

Answer 1

Answer:

500 W

Explanation:

Let resistance of each heater be

RΩ

Given that the power of each heater is 1000W when connecred across 240V.

So 1000=240

2R

⇒R=240

2

1000

Ω

When two heaters are connected in serises total resistance

2R=240

2

500

Ω

Then total power consumed =240

2

240

2

500=500W
